Built by riders, for riders, every board is handcrafted in the USA at Mervin Manufacturing—one of the most environmentally friendly snowboard factories in the world. These are the mad scientists behind Magne-Traction® serrated edges (turns ice into powder), Banana Technology (BTX) rocker (the original fun-enhancing shape), and some of the most durable, eco-conscious boards on the planet. From freestyle innovation to big-mountain domination, Lib Tech is always experimenting, always evolving, and always keeping snowboarding weird—in the best way possible. Not only do they push the limits of board tech, but they’ve also been paying and crediting independent artists properly since day one, something few other snowboard brands can claim.
